Our improvement is intended to obviate the disagreeable concussion in traveling over `rough roads, and consists of an upper back or support called a lazy-back attached by hinged uprights to the framework of the seat, when employed with a pair of springs at the sides of the seat for giving" the back a su port and forminoan agreeable arm rest for the occupant of the carriage.

As the back is pressed the helix of the springs unwind, while the flat surface thereof serves as a support to the arm resting on it.
